摘要
电磁兼容性指标已成为各类电子装备的关键指标;为满足加固便携式PXI机箱在环境恶劣的野战条件下的使用需求,需要对其进行针对性的电磁兼容性设计;通过分析加固便携式PXI机箱电磁干扰的来源,提出电磁兼容性设计方法,包括屏蔽、滤波、接地等。经试验分析,采取以上措施的加固便携式PXI机箱的电磁兼容性设计,能够满足国军标相关电磁兼容性要求。该机箱的电磁兼容性设计方法具有一定的通用性,可应用到其它电子装备的设计当中去。
EMC has become a key indicator of various types of electronic equipment. To meet the demand of users under iield conditions, the Ruggedized Portable PXI Chassis need to be targeted on electromagnetic compatibility design. By analyzing the sources of reinforcement electromagnetic interference of the Ruggedized Portable PXI Chassis, the artical targets to make a proposal on the electromagnetic eompatibil ity solutions, including shield, smoothing, ground connection, etc. Results of experiments show that the design of Ruggedized Portable PXI Chassis adopting the methods above is able to meet the requirements of GJB. The EMC design for this chassis has some versatility, which can be applied to other electronic equipment design.
